Accupro 14788693 Ball End Mill 0.203 in 4 Flute Solid Carbide

Product Description

The ACCUPRO 14788693 is a solid carbide ball end mill designed for precision milling operations in ferrous and hardened materials. With a 0.203 inch cutting diameter and a 4-flute medium flute geometry, it delivers smooth surface finishes and efficient chip evacuation in profiling, contouring, and finish milling applications. The AlTiN+ coating provides high-temperature oxidation resistance, making it well suited for dry or minimal-lubrication cutting conditions. The cylindrical shank measures 0.25 inches in diameter and the overall tool length is 2 inches, keeping the setup compact and rigid. Licensed machinists and CNC programmers working with die, mold, and precision component work are the primary users of this tool.

This ball end mill is sized for light to medium-duty contouring and 3D profiling work on CNC machining centers and manual mills. The 0.375 inch length of cut accommodates shallow-to-moderate depth passes on contoured surfaces, pockets, and complex geometry. The solid carbide construction and AlTiN+ finish make it a practical choice for cutting alloy steels, stainless, and hardened tool steels at elevated speeds. It is sold individually and is appropriate for shops requiring consistent, repeatable tooling in small-batch and production environments.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard materials
• AlTiN+ coating resists heat buildup, supporting higher cutting speeds and dry machining
• 4-flute medium geometry balances material removal rate with surface finish quality
• Ball end profile enables 3D contouring, profiling, and radius floor finishing
• Cylindrical shank compatible with standard ER collets and end mill holders
• Compact 2 inch overall length reduces deflection in close-tolerance setups

Compatibility

Designed as an OEM-style solid carbide ball end mill for use in standard cylindrical-shank end mill holders and ER collet systems accepting a 0.25 inch shank diameter.

Installation Notes

Installation is performed by machinists on CNC or manual milling equipment. Ensure the spindle is fully stopped and locked before changing tooling. Seat the shank fully into the collet or holder and torque the retention mechanism per the toolholder manufacturer specification. Confirm runout with a dial indicator before beginning a cut, as excessive runout accelerates edge wear on small-diameter carbide tools.
